PIPE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 589,362, dated August31, 1897.

Application filed-Pebruary i, 1895. Serial No. 537,245. (No model.)

To all whom it may concern: Be it known that I, JOHN S. MILES, a citizenof the United States, residing at Dayton, in the county of Montgomeryand State of Ohio, have invented certain new and useful Improvements inPipe-Couplings, of which the following is a specification.

My invention relates to improvements in couplings especially designedfor making connections with water-pipes or faucets, the connection beinginthe nature of a slip connectionv and designed to be applied to asmooth surface or surfaces without screwthreads or engaging projections.v

My invention consists in the constructions hereinafter described, andset forth in the claims. I

In the accompanying drawings, which form a part of this specification,Figure l is a par tial longitudinal sectional View of a device embodyingmy invention. Fig. 2 is a top or plan view of the same. Fig. 3 is a sideele vation of. the same show'n connected to a faucet, some of the partsbeing broken away and shown in vertical section to more clearlyillustrate the construction and operation. Figs. 4, 5, and 6 are viewsshowing a modification, Figs. 4 and 5 being each a sectional view, theparts in the different views being in different positions of adjustment,Fig. 6 being a detail view in perspective of the flexible sleeveremoved.

Like parts are represented by'similar letters of reference in theseveral views- My improved coupling consists, essentially, of an outercasing a, having at one end an inner projecting annular flange a and atthe opposite end being internally screvwthreaded, as shown at a Withinthis casing and fitted at the upper end to the annular flange a isaflexible sleeve 1), preferably of rubber. This sleeve 1) has aninternal bore 1), slightly larger than the pipe, faucet, or other waterconnection to which it is to be applied. It is further provided aboutthe middle of its length on its outer periphery with a deep-cut V-shapedgroove b In the lower end of the casing a is screwed the end of anipplec, internally screw-threaded at one end to fit the threads (1- in thecas ing and at the opposite end, as shown at 0, adapted to be connectedby screw-threads or otherwise to the pipe, hose, or other device whichis to be attached to the tube, faucet, or pipe with the smooth exterior.This nipple is also further provided with an enlarged flange or shoulder0 preferably hexagonal in shape, to which may be fitted a wrench orother device for turning the nipple in the casing a.

In operation the coupling, with the parts in the position shown inFig.1, is inserted onto the exterior of the pipe, faucet, or otherdevice d and the nipple c screwed into the casing, so as to compress thesleeve, which, by reason'of the V-shaped groove b will be forcedinwardly at a point opposite said groove and firmly impinge and bindupon the outer periphery of the device to which it is attached.

In Figs. t, 5, and 6 I have shown the construction of the sleevesomewhat modified, the modification consisting in providing said sleeveat the end toward the compressing, nipple with a depending lip b adaptedto hug the faucet or pipe on which the sleeve is placed. This dependinglip 19 is considerably smaller than the interior bore of the nipple 0,thus forming an annular chamber within the nipple about said dependinglip to receive the water and thus clamp said lip firmly against the pipeor faucet d by the hydrant-pressure, as shown in Fig. 5. \Vhen thisadditional element is employed, the V- shaped groove b may be placednearer the opposite end of the sleeve, the result being that twoimpinging points are secured upon the pipe or faucet instead of one. Amore stable connection is thus formed, the coupling being more firmlyheld against any lateral or oscillating movement on the faucet or ,pipe.The sleeve 1) is also preferably shouldered down, as shown at 11 to forma bearing-seat for the flange a, so that the end of said sleeve willstand substantially flush with the end of the casing and at the sametime furnish sufficient bearing against the flange a to securely holdthe sleeve in place when it is compressed by the nipple c.

I have found in practice that a device thus constructed can be connectedto faucets and pipes with smooth exteriors, so as to resist any ordinarypressure which may be applied thereto.

Having thus described my invention, I claim 1. A coupling consistingessentially of an outer casing, an inner flexible sleeve having aV-shaped groove and a depending lip, a movable nipple adapted to beforced in said casing and engage said sleeve, said nipple having aninterior bore slightly larger than the depending lip, substantially asspecified.

2. The combination with a tubular pipe, an outer casing having an innerprojecting flange, ant-flexible sleeve in said casing provided with acentral bore and having a V- shaped groove on its outer-periphery and adepending lip at its end opposite said flange, IS

In testimony whereof I have hereunto set 20 my hand this 6th day ofDecember, A. D.
